A Guide to Positive Behaviour Support in the NDIS

Positive Behaviour Support, or PBS, is more than a way of managing difficult situations. At its heart, it's a respectful, evidence-based way of understanding why someone might be using certain behaviours to communicate what they need. Under the NDIS, PBS is a key approach to improving a person's quality of life and reducing behaviours that may be causing concern for them or the people around them.

What is Positive Behaviour Support within the NDIS?

Positive Behaviour Support represents a real shift in thinking. Instead of simply reacting to a person's challenging actions, PBS works proactively to support their wellbeing and understand their unmet needs.

Think of it this way. If a plant is wilting, you don't paint the leaves green to make it look healthy. A good gardener gets to the root of the problem. Is it getting enough water? Is the soil right? In the same way, a behaviour support practitioner looks for the root cause of a behaviour to create real, lasting change.

The core idea: behaviour is communication

Every behaviour, no matter how it looks on the surface, is a form of communication. When someone can't easily express their wants, frustrations or needs through words, they might use actions instead. Those actions can be misunderstood or labelled as challenging.

A PBS plan teaches new, more effective ways to communicate and get those needs met. This isn't a quick fix or a form of discipline. It's a collaborative process, and that's why the NDIS funds it through the Capacity Building part of a plan: it builds a person's skills and the capability of their whole support network, including training and guidance for family, carers and support workers so everyone applies the strategies consistently.

What are the goals of a PBS plan?

The main goal is always to improve quality of life: greater happiness, independence and connection to community. A vital second goal is to reduce and, ideally, eliminate the need for restrictive practices by addressing root causes rather than symptoms.

Teaching new skills for better communication

Consider someone who becomes distressed in noisy places. The behaviour we see might be yelling, which is their way of saying "this is overwhelming". A PBS plan doesn't just try to stop the yelling. It teaches a replacement skill, which could look like:

• Learning to use a communication card that says "quiet, please"
• Practising a simple hand signal to show they need a break
• Getting comfortable asking for headphones before going into a loud space

The aim is to make the new skill a more efficient way of communicating than the old behaviour ever was. When that happens, the behaviour of concern often becomes unnecessary.

Creating supportive, proactive environments

A person's surroundings play a big role in their wellbeing, so a PBS plan also shapes the environments at home, at school and out in the community. This isn't about wrapping someone in cotton wool. It's about practical adjustments that head off common triggers, such as:

• Visual schedules: pictures or a simple list showing what the day looks like
• Consistent routines: daily tasks happening in a familiar, expected order
• Sensory adjustments: dimming bright lights or using noise-cancelling headphones for someone with sensory sensitivities

This stability eases anxiety and frees up energy for learning, growing and enjoying life.

How to access PBS in your NDIS plan

Getting behaviour support funded is very doable if you're well prepared, and the work starts before your planning meeting with evidence that tells a clear story about the need for specialist behaviour support.

Building your case with the right evidence

Your evidence should show your NDIS planner or local area coordinator how certain behaviours are linked to the person's disability and how they're getting in the way of important goals, like joining in community life or living more independently. Helpful paperwork includes:

• Reports from allied health professionals such as occupational therapists, speech pathologists or psychologists
• School or day program reports describing specific incidents, possible triggers and the effect on learning and socialising
• Medical letters from a GP or specialist linking the diagnosis to the need for behaviour support
• Your own records, such as a simple diary noting challenging situations, what was happening at the time and what followed

Where PBS sits in your funding

Positive Behaviour Support is funded under the Capacity Building part of an NDIS plan. In the NDIA's PACE system, behaviour support has its own dedicated support category, though older plan documents may group it under Improved Daily Living. If your current plan doesn't include it, you can request it at your next plan reassessment. Our NDIS capacity building guide explains how this budget works more broadly.

How you frame the request matters. You're not asking for funds to stop a behaviour; you're asking for resources that build skills and a better quality of life: new ways to communicate, better coping, more independence and community involvement. Behaviour and mental health often overlap too, and our guide to NDIS mental health support looks at that side of the picture.

Preparing for your planning meeting

With your evidence file ready, be direct in the meeting: ask for funding for a Functional Behaviour Assessment (FBA) and the development of a Positive Behaviour Support Plan. Back it up with specifics from your evidence, like a school report showing how sensory overload leads to missed activities and how a PBS plan could teach coping strategies.

Once funding is approved and you've found a practitioner, you'll put a service agreement in place. Our guide to NDIS service agreements explains what a good one should contain.

Choosing a qualified behaviour support practitioner

Finding the right practitioner is one of the most important decisions you'll make. You want someone who holds the right credentials and also builds genuine rapport with the participant and their family.

The NDIS Quality and Safeguards Commission runs a capability framework for behaviour support practitioners, with tiered levels that match practitioner expertise to the complexity of support needed:

Level	What it means
Core	Conducts assessments and develops straightforward plans, usually under supervision
Proficient	Works more independently across a broader range of situations
Advanced	Manages complex cases and provides supervision and mentoring to other practitioners
Specialist	Leads the most complex cases and contributes to research, policy and sector development

Questions to ask a potential practitioner

Questions worth asking when you first meet:

• What is your experience working with people with similar needs and goals?
• How do you involve the participant and their family in developing the plan?
• How will you train and support our family and support workers to put the plan into practice?
• How do you measure success, and what does progress look like to you?

A good answer to that last question focuses on quality of life and new skills, not just stopping a behaviour. If you're weighing up providers more generally, our guide to choosing the right disability support in Adelaide covers what to look for.

The PBS process, from assessment to review

PBS unfolds in clear stages, and it works as a continuous cycle rather than a straight line.

Stage 1: the Functional Behaviour Assessment

The FBA is the discovery phase. The practitioner gathers clues to understand the why behind a behaviour through direct observation in the person's everyday environments, interviews with family, support workers and teachers, and data collection to spot patterns (time of day, place, particular requests). The result is a working theory about what the person is trying to communicate.

Stage 2: designing the behaviour support plan

With the why understood, the practitioner works with the support network to create a personalised Positive Behaviour Support Plan. A quality plan is far more than a list of don'ts. It details proactive strategies to head off triggers, skill-building goals, and clear, safe reactive strategies for responding if the behaviour does happen, with de-escalation and safety as the top priorities.

Stage 3: implementation and ongoing review

A plan is only as good as its execution, so this stage centres on training and coaching for everyone involved, then regular monitoring: is the person picking up the new skills, and are the proactive strategies making a difference? As life changes, the plan is adjusted to match. Short team catch-ups, clear roles and direct training for support workers keep everyone working from the same playbook.

Common questions

How long does PBS take to work?

There's no magic number. Some people show positive shifts within a few weeks; others with more complex support needs may take several months or longer. What matters is steady, lasting progress, which depends on how consistently the whole support network uses the strategies.

What is the difference between a behaviour support practitioner and a psychologist?

A psychologist is a registered health professional who can diagnose and treat mental health conditions. A behaviour support practitioner has a specific focus: conducting Functional Behaviour Assessments and designing PBS plans for behaviours of concern, against the NDIS capability framework. Some psychologists are also approved practitioners, but the roles are distinct.

Will a PBS plan use restrictive practices?

Only as an absolute last resort, where there is a serious and immediate risk of harm. Any regulated restrictive practice must be documented in detail, formally approved and heavily scrutinised by the NDIS Quality and Safeguards Commission, and it must come with a clear strategy to phase it out by teaching safer ways to communicate. The end goal is always more freedom and a better quality of life.

Vana Care doesn't write PBS plans ourselves, but our support workers put them into practice every day across Adelaide, working closely with practitioners and families so strategies are applied consistently.
